ASH VACUUM AND SEPARATOR WITH FILTER CLEANING DEVICE

摘要

A vacuum system includes a filter cleaning mechanism which allows the filter to be cleaned without removal from the vacuum. This mechanism can include a carrying handle which is biased against the lid by a spring. The handle may be released from a vertical position, causing the handle to forcefully strike the lid and dislodge debris from the filter. The vacuum may include a spark arrestor disposed around the filter. The spark arrestor encloses the filter and surrounds the filter sides with a metal screen. The spark arrestor has holes formed in the bottom around the outer perimeter of the filter so that debris which is dislodged from the filter falls through the holes and into the vacuum canister.

1. A vacuum comprising:
a cylindrical canister for receiving and holding debris, the canister having enclosed bottom and sides and having an opening on a top thereof; a lid attached to the top of the canister, the lid being disposed to cover the opening and close the canister; a rigid cylindrical filter attached to a bottom of the lid such that the filter is disposed inside of the canister; an inlet port which receives a vacuum hose to allow debris to be collected in the canister; a vacuum motor attached to the lid, the vacuum motor drawing air into the canister through the inlet port and drawing the air through the filter and out of the canister; a striking lever pivotably attached to the lid; and a spring attached to the striking lever and to the lid, the spring biasing the striking lever against the lid such that a user may release the striking lever from a vertical position to cause the striking lever to forcefully strike the lid and thereby dislodge debris from the filter and deposit the debris in the canister.
